BeautifuL RainBow

The rainbow is made up of all the colors of the visible spectrum. We can also see these colors by using a prism. When white light passes through a prism, it is bent. Each color is bent differently. Red is bent the least, violet is bent the most. The white light spreads out into its colors. Each color of the visible spectrum can be seen.A rainbow is an arch of light exhibiting the spectrum colors in thier order, caused by drops of water falling through the air. it is seen usually in the sky opposite to the sun at the close of a shower and also in the spray of waterfalls.In the brightest or primary bow, often the only one seen, the colors are arranged with the red outside. Above the perfect bow is a secondary bow, in wich the colors are arranged in reverse order: this bow is dimmer, because of a double reflection within the drops.
